Course description
Lectures will be given on the properties of refrigerants at the cryogenic temperatures below -150 ° C, insulation technology, cooling technology, principles and applications of refrigerators, etc. Professor Okamura at Tokyo Institute of Technology mainly focuses on the fundamentals of superconducting phenomena, and researchers in charge of superconducting and cryogenic technology development at Toshiba Corporation give a lecture on the current state of R & D on cryogenic technology and superconducting applications. It is rare in Japan that lectures on cryogenic temperatures and superconductivity are conducted in the mechanical engineering department.
In the first half, in addition to the nature of superconductivity and the foundation necessary for the generation of extremely low temperatures, we will introduce an example in which a failure in the experiment triggered a serious discovery, an example where a small amount of flatfish triggered the Nobel Prize, an example in which the idea of reversal led to practical use, an example of using the real state (properties) instead of the ideal state learned in physics to high school, in the process of discovery of the superconducting phenomenon and the development of cooling technology.
In the second half, we will do exercises using a calculator as an attempt to apply the basics of heat transfer and thermodynamics learned in undergraduate schools to the design of actual cryogenic equipment. (Please bring a calculator for the class.)
We will also include as many lectures as possible on videos introducing superconducting phenomena and practical examples of superconducting equipment, and introducing the latest technological trends and research results.
Purpose of class
The purpose is to understand the phenomena of superconductivity that is anomalous behavior at very low temperatures where the quantum effects can not be ignored, and to cultivate a wide range of insights from the basics of superconductivity to cryogenic systems through the study of superconducting applications from the viewpoint of effective energy utilization.
In particular,
1. Students will be able to explain the nature of the superconducting phenomenon and the principle of cryogenic temperature generation.
2. Students will be able to perform a simple thermal design calculation in industrial equipment using a calculator, and to find out the technological development elements that are necessary for engineering as superconducting and cryogenic applications.
Goals and objectives
  1. Students can understand the technology that is required for engineering at a very low temperature.
  2. Students can understand the principles and concepts of the superconducting phenomenon.
  3. Students can understand the technology required to apply superconductivity to industrial equipment.

Evaluation method and criteria
We will do small exercises during the lecture. In addition, final exams for the entire course will be conducted at the final round of the lecture. That is, 100% evaluation will be made in the small exercises conducted during the lecture and the final exam throughout the entire lecture, and a total score of 60% or more will be passed.
The acceptance criteria (60%) is that, for a given problem, students can select the principle to be applied and can determine the solution and can calculate to reach the final solution generally correct.
